MAYNARD, OF SAME PLACE.

BENCH-VISE.

SPECIFICATION formingpart of Letters Patent N 0. 636,151, dated October31, 1899-.

Application filed April 14, 1 899.

To all whom it may concern:

Be it known that I, STANISLAS P. LEMAY, a citizen of the United States,residing at Manchester, in the count-y of Hillsborough and State of NewHampshire, have invented certainnew and useful Improvements in Bench-Vises; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use thesame.

This invention relates to Vises designed for light uses-such, forexample, as holding saws while being filed.

The objects of the invention are to provide a vise which shall bequickly attachable to a bench or other support and as quickly adj usted.

The invention will be fully set forth in the following specification andclaim, and clearly illustrated in the drawings accompanying and forminga part of the same, of which Figure l is a broken elevation showing thejaws in end view. Fig. 2 is a similar illustration showing the jaws inside view. Fig. 3 is a detached elevation showing the inner side of oneof the jaws.

Similar reference-letters designate corresponding parts in all views.

A is a casting having at one end a jaw B, and C is a casting having atone end a jaw D, said jaw D being made similar in form to the jaw B. Theoppositeend of said part 0 is designed to be pivotally connected to thepart A by a suitable pin E, and in order that said connection may besmoothly and neatly made the connecting end of the part C may berecessed on opposite sides, as at c 0, thus forming a tongue 0, adaptedto fit between the ears 0, of the part A, as seen by dotted lines inFig. 1.

The jaws B D are conveniently and quickly adjusted by a device embodyinga cam movement, which I will now describe.

A lever F passes through an elongated opening a, formed in the part A,and into a recess or socket 0 formed .in the part 0, wherein said leveris pivoted by a pin G. Said lever is adapted for vertical movementwithin the opening a of the part A, and when pressed downward the lowerportion of its pivoted end f will bear against the part 0, thus separatSerial No. 712,988. (No model.)

ing the jaws B D or permitting them to be separated, and by raising saidlever its curved shoulders f form contact with the thickened portion orcam 03 of the part A, which draws the jaws B D toward each other withgreat force, and in order to maintain the pressure thus obtained a pawlH is pivotally attached at h to said lever F and adapted to engagesuitable serrations (1 formed for the purpose upon the part A, as seenin Figs. 1 and 2.

The lower end of the part A may be bifurcated for the reception of alever J, pivoted therein by a pin K, the short end j of said lever beingadapted to close tightly against the projecting edge of a table orbench, clamp ing the same between itself and a shoulder a of said partA, which shoulder may, if de sired, be provided with one or more prongsa. to prevent a possible slipping. The long end of said lever J isprovided on its upper edge with serrations j with which a pawl L willengage for retaining the necessary pressure, said pawl being pivotallyattached to the part A by a suitable pin Z, and, if desired, a suitablefinger-piece Z may be formed upon the pawl for readily disengaging thesame from the serrations of the lever J.

Having described my invention, what I claim is i In a bench-vise, a pairof bars one longer than the other, pivotally connected, and eachprovided with a jaw adapted for contact one with the other, said longerjaw havinga thickened portion convexed on its outside and having avertically-elongated opening therein, a lever passing through saidopening and pivotally connected to said shorter bar, said lever having acurved projection on its under side for contact with the lower end ofsaid elongated opening and curved shoulders one on each side for contactwith the oonvexed projection of said longer bar, whereby said jaws shallopen or close by the movement of said lever, and means for retainingsaid lever in position to hold the jaws closed.

In testimony whereof I affix my signature in presence of two witnesses.

hi STANISLAS P. X LEMAY.
